Alpine Lake Science and Management
Most of Idaho’s backcountry lakes were historically fishless. Trout were first stocked into backcountry lakes as early as the late 1800’s as settlers began to arrive in Idaho. However, stocking didn’t become widespread until the 1920s. Over the decades, Idaho Fish and Game's stocking practices have been slowly refined as new information becomes available, but the tradition of providing great alpine lake fishing continues today.
Stocking Triploid Cutthroat Trout
Can triploid cutthroat trout improve fishing in backcountry lakes? Biologists completed a three-year study of mountain lakes to compare two kinds of trout used for stocking.
